y if Patented Feb. 28, 1933 UNITED STATES PATENT OFFICE ERNST POWER, OFGIDGAU, GERMANY TIME RECORDING DEVICE Application Med December 28, 1829,Serial 1T0. 417,155, and in Germany September 19, 1928.

The invention relates to a time controlling device for cash registeringapparatus, connected with the cash registering apparatus in such a.manner, that a print of the 5 time indication on the cash controllingstrips is effected independently of the other mechanism by a'clockworkof the time printing device Within definite periods, while independentlyof the other driving mechanism of 9 the cash registering apparatus aclockwork of any suitable type will actuate tvpe bars, which will markthe time on the control strip of the cash registering apparatus;

It has already become known to arrange in cash registering apparatustime printing mechanism, but these arrangements possess the drawback ofdeficient survey and a restriction of their function, which did not ad-W mi't the yariety use as with the subject matter or i l -ication.

The invention shows the advantage of Lie of the time printing devicedependently of the h register mechanism contradis tinction known timeprinting devices, which are depezon the cash registering mechanism.means the novei arrangement a considerable incr se the supervisionthrough the cash regis' g apparatus. an increase of economicalacvantages, the indication of the time within the of the supervision ofcash transactions, the education to arational use of salesmen, thesimultaneous use as controlling block for the employees, the furtheranceof test and trial purchases and supervision over fraudulentmanipulations with the till outside business hours is ob tained,

The essential characteristic feature'of the invention be seen'in themethod of connecting a control printing clock with a cash registeringapparatus in order to obtain the I print of the time indication on thecontrolling strip of the cash register for the purpose of recording theitem within definite periods.

Some modes of execution of the arrangement according to the inventionare illustrated in the drawings by way of example, with 'D of the Figureout restricting the invention to the examples shown.

Figure 1 is a perspective view of a suit able device.

Figure 2 is a side elevation partly in'section on line AB of Fi re 1,

Figure 3 is a vertica section through the system of guiding lever IFigure 4 shows the diagram of an arrangement of time marks on anenlarged scale, 1 Figures 5 and 6 show a modification, name- Figure 5 aperspective view with the frontplate removed, and

Figure 6 a longitudinal section on line G 5 Figure '2' illustratesanother modification, being a perspec ive view Figure 8 is a. transversesection on line E F of Figure 7, and a Figure 9 shows by way of examplethe construction and action of the pressure bolt 32 of Figures I and 8Qabutment rails 2 are axiaily arranged m t e container 1 and they aresecurely guieeo by grooves 3. Guiding forks 4 are secured in the centreof the abutment rails 2, into which engage corresponding guiding rollers5 each provided at the head of a segment G (Figure 2). The segments 6,0fwhich so one is arranged beneath each abutment rail, are pivotallymounted at 7 and they are subject to the action of the tension springs 8and return springs 9 and they terminate in toothed segments 10, Eachtoothed segment 10 is engaged by a driving disc 11, connected withclockwork and being rotated clockwise The various arcs of the drivingdisc 11 are provided each time with teeth only over one eighth of theirperiphery, so that always one abutment rail after the other is advanced,while all rails will touch at the point 12 (Fig ures 1 and '22). Thisaim of touch is the controlling strip 13 of a cash. registering apparatus in front of which strip the customary inked ribbon 14 is providedThe operation is as follows:

The driving disc 11 (Figure 2) engages the toothed segment 10 and movesthe latter to gether with the abutment rail 2 against the action ofthespring 8 backwards for such a time, until the roller 5 has reached thepoint 15. At this moment the teeth of the driving disc disengage thoseof the segment 10, the

5 spring 8 snaps back and advances the roller 5 to the point 16 and thehead of the abutment rail 2 will beat at 12 against the inked ribbon 14and the controlling strip.

. As the head of the said rail is provided 19 with a type of the timemark, the latter will be printed on the controlling strip; The returnspring 9 acts upon the nose 17 and returns the segment 6 toitsinoperative position. An accurate adjustment is obtained by 35 means ofthe stop 18, the abutment rail will thus at once release the controllingstrip again. No figures are used as time indicating signs, but thediagramrepresented in Figure 4. As the clock continues moving, while the343 controlling ribbon is often at rest, the marks would be printed oneon top of the other and they would become indistinct. By using thepresent diagram the picture 19 {Figure 4) will be formed. v

In the modification illustrated in Figures 5 and 6 the body of the clock20 carries a bolt supporting disc 21, which is turned clockwise by meansof a clockwork. On the said disc 21 the ressure bolts 22 are arrangedaxially and isplaceable; they are subjected to the action of-the tensionsprings 23. The printing or stamping bolts 22 are provided with stoppins 24, which will engage the front edge 25 of the disc 21, and whilethey penetrate through said disc they terminate in guiding rollers 26.The scent 27 attached to the body'ot the clock is situated in the pathof the rollers 26.

The operation is as follows:

As soon as the guiding rollers 26 are in engagement with t e segment 27(Figure 5) they are forced back together with the printing boltsaccording to the curve of the segment until the termination of the curveis 5 reached at 28. The tension springs23 will then snap the boltagainst the inked ribbon and the controllin strip thus causing the touchand print 0 the sign or mark. The

double springs 29 efiect an instantaneous release of the controllingstrip. With this modification toothe use of the diagram of time marksaccording to Figure 4 is recommendable.

A third modification of the invention is il- 5 lustrated in Figures 7and 8.

The body 200i the clock is provided with the disc 30 turned clockwisebye clockwork and carrying the se cuts 31. Above that disc 30 theprinting it 32 carrying the time marks is displaceably mounted'in knomanner in such a way, that a roller-'33 atgaiched thereto lies in thepath of the segment The operation of the device is as follows: 1. .31will force back the printi,eee,aec

ing bolt 32 against the action of the tension springs 34 by means of theroller 33 for such a time (Figure 7) until a recess 35 of the sement'passes. Then the bolt 32 will snap bac causing a print and touch on 13and 14: and it is returned into its initial position by means of thedouble springs 36. If the diagram of time marks according to Figure 4 isused, eight discs 30 arerequired' according to the. number of marks.

But the rinting bolts may be so constructed that it is provided at itstouching or engaging end with a disc carrying the eight time marks,which disc is turned through the segments 31 according to the time andis 30 caused to print at 13 and 1 4.

In the modifications shownin Figures 1 and 5 there will be usedonlyeight hour marks correspondin to the eight hours business day andalso or the purpose of rendering the entire driving mechanism propersimpler.

Figure-7 shows the construction of a printing bolt, which will beactuated by the tour segments 31 each quarter of an hour, if the disc 30is turned each hour. All modifica- 99 tions shown in Figures 1, 5- and 7can be provided without any dificulty with any subdivision governed byrequirements and by designing them as time printing devices, and theyonly show possible constructions by way i of example. i

In the constructional example shown in the drawin s only four segmentsare shown in Fi re and a device for only eight timein icating marks inFigure 9 for the sake of 51w clarity.

In practice a stamping mechanism is de sirable which prints five minutemarks at the end of every five minutes and at theisame time stamps thecorresponding hour indicat- 5 ing marks at the end of each hour. Forthis purpose an arrangement as shown in Figure ,for. example, isprovided with a printing bolt having twelve time-indicating marks, thesaid bolt being actuated by means of a. clock-work mechanism eve fiveminutes. Besides these time indications the hours would be indicated bya similar arrangement, in which the appropriate hour-in catin mark isreleased and printed at the end 0 each hour. The resultis apparent fromthe drawing of the record strip.

For instance on the printing bolt 32 is revided at its rintin providedin t is corresponding to the desired division of time, and the said earwheel is retained in its position of rest y means of pawls 38 andlocking spring 39. On the axis of the ar wheel. a in the rear ofthe-printing bolt 32 is mounted rigidly the mark1ng'disc40 provided.with printing t On one side of the bearing for the prin mg bolt apushing angle lever 41 having a tension spring43 is arran d in such amanner that on tensioning thew ole print ing bolt 32, it is ushed into atooth-gap of the gear wheel 3 while a catch 42 on the printing bolt 32will maintain the angle .41 in the proper position. 1

At the tensioning 34 of the printing bolt 32 the gear wheel 37 isadvanced towards the angle 41. This latter will push and turn the gearwheel 37together with the, disc 40 carrying the printing types, untilunder the ac- 10 tion of the locking spring 39 the pawl 38 will snapinto the next tooth -gap while at the same time also the termination ofthe tensioning of the printing bolt is reached. When the printing boltis flung back into its position of rest the pushing angle too will bereturned to its former position of rest by means of its tensioningspring 43 and it is ready in front of the next tooth-gap.
